2 Claims.

This invention relates to a wedge and a combination of a wedge with a flanged roll cap. for

use in the capping of wooden rolls for use in textile, paper, and other machinery.

The principal objects of the invention are to provide a wedge, separate from the roll cap, for forcing into the end of a roll in the direction of its grain so as to apply pressure and compression to the wood outside the wedge and inside the flange on the cap, thereby assisting very materially in holding the parts in place and to provide a Wedge circular in shape and concentric with the roll cap which can be placed in position temporarily and forced into the roll by the press means for setting the roll cap'in place.

Other objects and advantages of the'invention will appear hereinafter.

Reference is to be had to the accompanyin drawing, in which I Fig. l is a diametrical sectional view, on the line l--l of Fig. 2, of the end of a wooden roll for use in the textile or paper industry with a preferred embodiment of this wedge and a roll cap shown in connection therewith;

Fig. 2 is an end view of the same assembled;

Fig. 3 is a view similar to Fig. 1 showing the first step of the setting of the Wedge in position;

Fig. 4 is an ordinary-view showing a step in the method of assembling the parts before they come to their final position, and

Fig. 5 is an end View of the Wedge as indicated by the arrow 5 in Fig. 3.

This invention can be used in connection with several kinds of metal end caps for wood rolls used in the textile and paper industries, but it is shown herein as used in connection with the particular roll cap shown in Patent No. 1,543,381, patented June 23, 1925. In that patent wooden wedges could be forced in to the end of the roll, in the direction of the grain, having a certain anchoring effect. In this case it is desired that a substitute for that Wedge be provided which will compress the wood throughout its entire circumference between the Wedge and the concentric flange of the roll cap and thus securely anchor the cap in position.

For the above purpose the Wooden roll Ill, having a longitudinal grain, is provided with a wedge ll set into the wood concentric with the shaft 12. This wedge is circular and in complete circular form. On one end it has what may be considered a sharpened wedge-shaped end I3 and the other is in a plane l4. Withthe wedge centered and just driven in by hand enough to hold it, as shown in-Fig. 3, the metal end cap l5 having a cylindrical integral flange l9 with a sharpened end i8 is placed over the wedge H and centered with respect thereto. Then the device is put into a press and the cap forced in until the surfaces i6 thereof engage the butt end of the wedge H. Ordinarily there are three of these surfaces it but, of course, any number can be employed. After that contact takes place, the Wedge II and flange l9 are forced along the grain of the wood into final position therein, as shown in Fig. 1.

The inside cylindrical hub of the end cap is intended to be forced down to the end of a reduced cylindrical portion 2| of the shaft 12. Also the wedge H is forced to its final point together with the flange l9.

It will be seen that this wedge and this flange are both completely circular and they are concentric with each other. After the cap is brought final position, as shown in Fig. l, is along the grain of the wood and the two wedge ends l3 and I8 are toward each other from the inside of the former and the outside of the latter. The wood necessarily will be compressed and a permanent pressure placed upon it to act to hold the parts in the position shown, even after long usage. This assists in holding the end cap firmly in position, which is necessary in this art.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. The combination of a flanged end cap for a wood roll, with a separate wedge therein engaging at its end an inner surface of the end cap for compressing the wood of the roll between the wedge and the flange on the cap.

2. The combination with a wood roll and an end cap having a circumferential cylindrical sharp ended integral flange embedded in the roll with the grain of the Wood, and having a series of integral inward projections, of a cylindrical Wedge of smaller diameter than said flange and concentric therewith and having a circular wedge shaped end and a flat opposite end adapted to be engaged by said projections, whereby said Wedge Will be driven into the end of the roll by the driving in of the cap.
